android - Barometer App - Where to from here? -

i working on basic barometer app , have run slight snag. want take data being received , have run through text view have setup pressure variable. here code point:

import android.app.activity; import android.hardware.sensor; import android.hardware.sensorevent; import android.hardware.sensoreventlistener; import android.hardware.sensormanager; import android.os.bundle; import android.view.view; import android.widget.button; import android.widget.textview;  public class barometer extends activity { textview barotext, timetext; button refresh;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.barometer_layout);     uivars();      sensormanager sensormanager = (sensormanager) getsystemservice(sensor_service);     sensor sensor = sensormanager.getdefaultsensor(sensor.type_pressure);      sensormanager.registerlistener(new mylistener(), sensor,             sensormanager.sensor_delay_normal); }  public void uivars(){     barotext = (textview) findviewbyid(r.id.pressuretxt);     timetext = (textview) findviewbyid(r.id.timetxt);     refresh = (button) findviewbyid(r.id.barorefreshbtn); }  class mylistener implements sensoreventlistener {     @override     public void onaccuracychanged(sensor sensor, int accuracy) {         // todo     }      @override     public void onsensorchanged(sensorevent event) {         long timestamp = event.timestamp;         float value = event.values[0];         // values     } } } 

i understand silly missing wanted second set of eyes looking @ it. - if running android studio ide.

this should work:

@override public void onsensorchanged(sensorevent event) {     long timestamp = event.timestamp;     float value = event.values[0];      string valuestring = string.valueof(value);     barotext.settext(valuestring); } 

if want display value in textview.
